In conjunction with Lukas I’ve been working on a complete rewrite of libmusicbrainz to support the new Web Service v2 released alongside NGS. I’m happy to announce the official release of this new library (libmusicbrainz4).

The library is written as a relatively simple parser for the results from the Web Service, with as little logic as possible. This should mean it is easy to maintain to keep in step with any changes in the schema for the XML Web Service.

The main interface is a C++ class ‘CQuery’, that returns a Metadata object containing a parsed version of the response. There is also a C interface that loosely wraps the C++ classes.

Using the library requires a good understanding of the queries and responses to and from the Web Service. Download the library, or browse the online documentation or generate the documentation from the source with make docs.

If you find any issues, please report them using JIRA (under the project ‘libmusicbrainz’).

I will follow the musicbrainz-devel mailing list and the #musicbrainz-devel IRC channel on freenode in order to answer questions if at all possible.

Thanks.

Andy

I’m reposting this from the MusicBrainz-devel mailing list:

Version 0.2 of RBrainz, a Ruby library to access the MusicBrainz web service, has been released.

With this release all of the features provided by the MusicBrainz web service are supported. The most notable changes from the previous beta releases are:

* Querying of collections

* User authentication and querying of user information

* PUID submission

* Support for label aliases

* Complete support of the MusicBrainz metadata scheme 1.2 (including the upcoming tagging)

A complete list of changes can be found at

I like to thank Nigel Graham who joined development and implemented important parts of the library. Without him this complete release wouldn’t have been so early possible.

The official python bindings for MusicBrainz, python-musicbrainz2 have been released. Starting with this version, the API is stable and the package is considered ready for general use.

Thanks go to everyone who participated in the development, most notably Lukáš Lalinský who ported picard-0.7 to python-musicbrainz2, created binary packages and has contributed bug reports and patches.

The following changes were made for 2.1.1:

• Return special TRMs for special conditions for TRM generation:
  

  c457a4a8-b342-4ec9-8f13-b6bd26c0e400 — Sigserver busy and overloaded
  f9809ab1-2b0f-4d78-8862-fb425ade8ab9 — Source file is too short to calculate TRM
  7d154f52-b536-4fae-b58b-0666826c2bac — File is silence

• If the TRM signature server becomes overloaded, it will now start
  returning HTTP 503 error codes and the TRM generator will catch that
  and return the Sigserver busy TRM shown above.

The following changes were made for 2.1.0:

• Moved the python bindings into a new seperate project
• rewrote the mp3 duration detection code to be more robust by making it vastly easier. In the process the bitzi related code has been tossed. This should make the libary smaller and the mp3 duration checking faster.
• Due to the bitzi code being removed, the SHA1 and Bitprint related functions have been removed.
• Added query items for Release Dates/Countries, Amazon Asins and Amazon cover art URLs
• Move include files into include/musicbrainz so that the example files will compile outside of the libmusicbrainz client source tree.
